[0154] FIG. 1B is a schematic diagram of SBFD according to an embodiment of the present disclosure. As shown in FIG. 1B, in order to solve the problem that the uplink transmission resource of TDD is less, resulting in a longer feedback delay of TDD, the related technology introduces a new duplex technology based on TDD, that is, sub-band non-overlapping full duplex (SBFD). Compared with TDD, SBFD introduces an uplink sub-band on the frequency domain resource corresponding to the downlink symbol and / or flexible symbol, which can be used for uplink transmission. Therefore, SBFD can effectively improve the uplink coverage and reduce the feedback delay.

[0155] [According to Rule 91, correct 15.10.2024] In some embodiments, in the SBFD discussion of 3GPP (3rd Generation Partnership Project) Release 19, for the physical downlink shared channel (PDSCH), the transport block size (TBS) is determined according to the PRB (Physical Resource Block) that can be used for downlink transmission in the PRB indicated by signaling. That is, for PDSCH, on the SBFD slot, the RB (Resource Block) included in the uplink sub-band and the guard band (if the standard defines the guard band) is not used to determine the TBS of the transmission signal.

[0156] In some embodiments, the TBS calculation method specified in the related technology protocol includes the following steps:

[0157] Step 1: Determine the number N of resource elements (REs) used for PDSCH transmission in a slot RE :

[0158] First, determine the number N' of REs (Resource Elements) in a PRB (Physical Resource Block) allocated to PDSCH RE , which is calculated by the following formula RE

[0159] wherein is the number of subcarriers included in a PRB, is the number of symbols allocated to PDSCH in a slot, The number of REs used by the demodulation reference signal (DM-RS) in each PRB. The overhead of configuring xOverhead (in PDSCH-ServingCellConfig) for higher-level signaling.

[0160] Secondly, determine N. RE :N RE =min(156,N′) RE )·n PRB , where n PRB The number of PRBs allocated to PDSCH.

[0161] [Corrected according to Rule 91, 15.10.2024] Step 2: Calculate the non-quantified intermediate variable N info =N RE ·R·Qm·v, where R is the target code rate of PDSCH, Q m v represents the modulation order of the PDSCH, and v represents the layer number of the PDSCH.

[0162] Where, if N info If the value is ≤3824, proceed to step 3; otherwise, proceed to step 4.

[0163] Step 3: If N info If the value is ≤3824, perform the following steps:

[0164] (1) Calculate the intermediate variables for quantification in

[0165] (2) According to Table 1 below, find the value not less than N′. info The maximum value is taken as TBS.

[0166] Step 4: If N info >3824, perform the following steps:

[0167] (1) Calculate the intermediate variables for quantification in The round operation represents rounding.

[0168] [Corrected according to Rule 91, 15.10.2024](2) If R≤1 / 4, in Otherwise, if N info >8424, wherein otherwise,

[0169] FIG. 1C is a schematic diagram illustrating a PDSCH slot aggregation scenario according to an embodiment of the present disclosure. In some embodiments, for a communication scenario of PDSCH slot aggregation (PDSCH slot aggregation), which can also be referred to as a communication scenario of PDSCH repetition (PDSCH repetition), it is unclear which type of slot to use to determine the TBS (PRB resource block size of downlink transmission) using the number of PRBs available for downlink transmission on the slot. As shown in FIG. 1C, the PDSCH slot aggregation level is 2, which is allocated on a downlink slot and a sub-band full duplex (SBFD) slot, respectively, and the frequency domain resource allocation (FDRA) signaling indicates that the frequency domain resource spans two downlink sub-bands and one uplink sub-band in the frequency domain. According to the method provided in the above embodiments, there are the following two ways to determine the TBS:

[0170] (1) determining the TBS according to the number of PRBs available for PDSCH on the downlink slot;

[0171] (2) determining the TBS according to the number of PRBs available for PDSCH on the SBFD slot.

[0172] Among them, method 1 can cause the actual code rate (the number of bits transmitted or processed per unit time) to be higher than the target code rate, resulting in poor PDSCH slot aggregation performance; method 2 can cause the actual code rate to be lower than the target code rate, resulting in over-good PDSCH set performance, i.e., resulting in resource waste. Therefore, the method for determining the TBS in the PDSCH slot aggregation scenario is proposed in the present embodiment to determine the TBS determination method in the PDSCH slot aggregation scenario.

[0173] In some embodiments, the TBS determination method for PDSCH slot aggregation includes: determining the TBS according to the number of available PRBs on the first slot of PDSCH slot aggregation; determining the TBS according to the number of available PRBs on the first available slot of PDSCH slot aggregation; determining the TBS according to the number of available PRBs on the SBFD slot; determining the TBS according to the number of available PRBs on the non-SBFD slot; determining the TBS according to the number of available PRBs on the SBFD slot and the non-SBFD slot to which PDSCH slot aggregation is allocated, and the number of available PRBs on the two types of slots; and determining the TBS according to the number of available PRBs on the specified slot type (SBFD slot or non-SBFD slot).

[0174] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a communication method, and the method comprises:

[0175] In step S2101, the network device 102 sends first information to the terminal 101.

[0176] In some embodiments, the terminal 101 receives the first information.

[0177] In some embodiments, the first information is used to instruct the terminal to receive a first signal in at least one time unit.

[0178] In some embodiments, the first signal is carried by a PDSCH resource.

[0179] For example, the first signal is a downlink transmission signal carried by a PDSCH resource, the network device instructs the terminal to receive the first signal in a time domain resource by the first information, and the terminal can receive the first signal in the corresponding time domain resource by the PDSCH resource based on the first signal. The time domain resource indicated by the first signal includes one or more time units, that is, the terminal needs to receive the first signal sent by the network device in the time range corresponding to the one or more time units by the PDSCH resource. If the time domain resource corresponds to multiple time units, the multiple time units can be continuous time units in the time domain or non-continuous time units in the time domain. For example, in the PDSCH time slot aggregation communication scenario, the terminal needs to receive the first signal sent by the network device in multiple time units.

[0180] It should be noted that the time unit in the present embodiment can be a time slot, and can also be a symbol used to indicate time.

[0181] For example, the first signal is a downlink transmission signal sent by the network device to the terminal, the first signal is carried by a PDSCH resource, and the terminal receives the first signal sent by the network device in the time range corresponding to at least one time unit in the frequency range corresponding to the PDSCH resource. The first signal can be a reference signal, a synchronization signal, a control signal, etc.

[0182] In some embodiments, the name of the first information is not limited, for example, it is “time domain resource information”, “signal resource information”, “signal transmission time information”, etc.

[0183] In some embodiments, the at least one time unit includes an SBFD time unit and a non-SBFD time unit.

[0184] For example, the first signal is carried on a PDSCH resource, and the PDSCH transmits the first signal in a time slot aggregation manner. By aggregating multiple time slot resources, the PDSCH can increase the amount of data transmitted per signal transmission, thereby improving throughput. Meanwhile, the PDSCH transmits the first signal in a time slot aggregation manner, which can reduce latency and improve transmission efficiency of the first signal. The PDSCH time slot aggregation is allocated on the SBFD time unit and the non-SBFD time unit.

[0185] The SBFD time unit is a time unit configured with an uplink sub-band, and the non-SBFD time unit is a time unit without a configured uplink sub-band, that is, the non-SBFD time unit is a downlink time unit and / or a flexible time unit. The non-SBFD time unit is a time unit configured only with a downlink sub-band. Flexible resource configuration can be performed based on signaling on the SBFD time unit. The SBFD time unit can span one or more OFDM (Orthogonal Frequency Division Multiplexing) symbols and can be configured to be continuous or discontinuous in the time domain. The non-SBFD time unit is a non-flexible configured time unit, including a larger or fixed time-frequency resource block, to indicate a non-flexible resource type.

[0186] It should be understood that the SBFD time unit is a time unit in which the network device performs SBFD operation, and the non-SBFD time unit is a time unit in which the network device does not perform SBFD operation, or in other words, the non-SBFD time unit is a time unit in which the network device performs TDD operation. The non-SBFD time unit can include at least one of the following: an uplink time unit, a downlink time unit, and a flexible time unit. In the embodiment, the PDSCH resource is used to indicate reception of the first signal. Therefore, in the embodiment, the non-SBFD time unit is a time unit in which the terminal can receive the first signal, that is, in the embodiment, the non-SBFD time unit is a downlink time unit and / or a flexible time unit.

[0187] In step S2102, the terminal 101 determines the first time unit according to the first information.

[0188] For example, the first time unit can be part or all of the time units in the at least one time unit indicated by the first information. After determining the time range corresponding to the at least one time unit based on the first information, the terminal can determine the first time unit from the at least one time unit based on a set criterion. For example, the terminal can determine the first time unit in the at least one time unit in the time domain as the first time unit. In this case, the terminal can determine the first time unit in the at least one time unit in various ways. For example, the first time unit in the terminal can be indicated by signaling information sent by the network device. The terminal can also determine a non-SBFD time unit and / or an SBFD time unit on the at least one time unit as the first time unit based on a preset configuration or a preset criterion.

[0189] In some embodiments, the first information includes an FDRA field, and the step S2102 includes:

[0190] The terminal determines the first time unit according to the FDRA field.

[0191] For example, the network device multiplexes the first bit information in the FDRA field to indicate which time unit type the terminal uses to determine the TBS of the first signal. The terminal determines the first time unit from the at least one time unit according to the first bit information. For example, each bit in the bit pattern corresponding to the FDRA field is only associated with a resource block group (RBG) overlapping with a downlink subband. The time unit corresponding to the resource block overlapping with the downlink subband can be determined as the first time unit by the first bit information corresponding to the FDRA field. The first time unit is indicated by the first bit information corresponding to the FDRA field, thereby reducing signaling overhead and improving transmission efficiency.

[0192] In some embodiments, the step "the terminal determines the first time unit according to the FDRA field" includes:

[0193] The terminal determines the first time unit according to one or more bits corresponding to the highest bit of the FDRA field.

[0194] The first bit information is the bit information corresponding to the highest bit of the FDRA field. The first time unit is indicated by the bit information corresponding to the highest bit of the FDRA field, which ensures that this information can be preferentially received and processed by the terminal, so that the terminal can quickly respond and determine the corresponding first time unit. For example, the RIV (Rank Indicator) of the FDRA field plus 1 bit or 2 bits is used to indicate the first time unit, and the terminal is controlled to understand the first time unit indicated by the FDRA field by RRC (Radio Resource Control) information.

[0195] In some embodiments, the method further comprises:

[0196] The terminal determines the first frequency resource corresponding to the non-SBFD time unit according to the FDRA field;

[0197] The terminal determines the second frequency resource corresponding to the SBFD time unit according to the FDRA field and the downlink sub-band;

[0198] The terminal determines the frequency resource corresponding to the first time unit according to the first frequency resource and the second frequency resource.

[0199] In an example, the FDRA field is used to indicate the time unit position corresponding to the non-SBFD time unit and the SBFD time unit, and the terminal determines the second frequency resource corresponding to the SBFD time unit and the first frequency resource corresponding to the non-SBFD time unit from the frequency resource indicated by the FDRA field according to the time unit position, and takes the first frequency resource and the second frequency resource as the frequency resource corresponding to the first time unit, for calculating the TBS of the first time unit.

[0200] In some embodiments, the above step S2102 comprises:

[0201] The terminal acquires a time domain resource allocation (TDRA) table;

[0202] The terminal determines the TDRA field corresponding to the first information;

[0203] The terminal determines that the time unit indicated by the TDRA field in the TDRA table is the first time unit.

[0204] In an example, the terminal is configured with a TDRA (Time Domain Resource Allocation) table, which is used to indicate the time domain resource allocation of a PUSCH (Physical Uplink Shared Channel) and / or a PDSCH (Physical Downlink Shared Channel). The TDRA table provides a flexible way to configure the time domain resource, including the starting symbol, duration, and mapped resource type of the PUSCH and the PDSCH. Through the TDRA table, the network can flexibly adjust the resource allocation according to the real-time service demand and channel condition, and achieve higher spectrum utilization. In the embodiment, a column of information is added to the TDRA table configured by the terminal. The column of information is used to indicate one or more candidate first time units. The TDRA field corresponding to the first information is used to indicate a time unit from the one or more candidate first time units as the first time unit. The terminal determines the TBS of the first signal according to the number of available frequency resources on the first time unit. The network side indicates a time unit from the one or more time units as the first time unit through the TDRA field corresponding to the first information.

[0205] In some embodiments, the network device can determine the first time unit in the network device based on the manner in which the terminal determines the first time unit, and determine the TBS based on the number of available frequency resources on the first time unit.

[0206] In step S2103, the terminal 101 determines the TBS of the first signal according to the frequency resources corresponding to the first time unit.

[0207] In some embodiments, the first time unit is a time unit in the at least one time unit.

[0208] In an example, the terminal needs to determine the TBS of the first signal according to the at least one time unit indicated by the first information, so as to make the terminal determine the amount of resources required to receive the first signal, ensure the PDSCH time slot aggregation performance while avoiding resource waste, and at the same time, the terminal can perform downlink scheduling and decision based on the TBS of the first signal, help the terminal to determine when and how to receive the first signal, and reduce communication loss.

[0209] The terminal determines the TBS of the first signal according to the number of corresponding frequency resources on the first time unit, where the frequency resources on the first time unit are PDSCH resources used for receiving the first signal, that is, the TBS of the first signal is determined according to the number of frequency resources available for receiving the first signal (hereinafter referred to as the number of available frequency resources) on the first time unit. For example, if the corresponding frequency resources on the first time unit are non-SBFD time units, the TBS of the first signal can be determined according to the number of downlink frequency resources and / or the number of flexible frequency resources on the non-SBFD time units; if the corresponding frequency resources on the first time unit are SBFD time units, the TBS of the first signal can be determined according to the number of available frequency resources on the SBFD time units. Wherein, after the terminal determines the frequency resources corresponding to the first time, the calculation method of the terminal for calculating the TBS of the first signal based on the frequency resources is not limited, and the calculation method of the TBS in the above embodiments can be used for calculation.

[0210] In some embodiments, the first time unit includes at least one of:

[0211] The first time unit in the at least one time unit;

[0212] The first non-uplink time unit in the at least one time unit;

[0213] The non-SBFD time unit in the at least one time unit;

[0214] The SBFD time unit in the at least one time unit;

[0215] The first non-SBFD time unit in the at least one time unit;

[0216] The first SBFD time unit in the at least one time unit.

[0217] For example, the first time unit includes one or more, and the corresponding method for determining the frequency resources based on the first time unit includes at least one of:

[0218] Method 1: The first time unit is the first time unit in the at least one time unit, and the first time is the earliest time unit in the at least one time unit in the time domain.

[0219] Optionally, if the first time unit of the PDSCH time slot aggregation is a non-SBFD time unit, that is, the first time unit is a non-SBFD time unit, the TBS is determined according to the number of PDSCH resources indicated by the first information on the first time unit, wherein the first information can include a FDRA (Frequency Domain Resource Allocation) field, and the network device controls the distribution of data in the frequency domain through the FDRA field, including allocating specific subcarriers to the terminal for use, so as to fully fine resource management and improve frequency efficiency, and the network device determines the TBS of the first signal according to the number of frequency resources indicated by the FDRA field.

[0220] If the first time unit of the PDSCH time slot aggregation is an SBFD time unit, the TBS is determined according to the number of frequency domain resources available for downlink transmission in the frequency resources indicated by the FDRA field on the first time unit.

[0221] The TBS of the first signal is the transport block size information used by the terminal to receive the first signal, so the TBS is the transport block size corresponding to the downlink subband, and on the SBFD time unit, it can include at least one of the following: uplink subband, guard band, and downlink subband, wherein the uplink subband and / or the guard band cannot be used for downlink transmission, and if the frequency resources indicated by the FDRA field include frequency resources located in the uplink subband and / or the guard band, these frequency resources cannot be included in the calculation of the TBS.

[0222] For example, FIG. 2B is a schematic diagram of a TBS determination method according to an embodiment of the present disclosure. As shown in FIG. 2B(a), based on the first information indicating that the first time unit of the PDSCH time slot aggregation is a downlink time unit in the above embodiment, the TBS is determined according to the number of PRBs indicated by the FDRA field in the first time unit, that is, n PRB is the number of PRBs indicated by the FDRA field.

[0223] For example, as shown in FIG. 2B(b), the first information indicates that the first time unit of the PDSCH time slot aggregation is an SBFD time unit, and the TBS of the first signal is calculated according to the number of PRBs indicated by the FDRA field, minus the number of PRBs included in the uplink subband and / or the guard band on the SBFD time unit.

[0224] In some embodiments, the terminal does not expect the first information to indicate that the first time unit of the PDSCH time slot aggregation is an uplink time unit, and if the terminal identifies that the type of the first time unit is an uplink time unit, the terminal considers it as an error case.

[0225] Manner 2: The first time unit is the first non-uplink time unit in the at least one time unit, and the first non-uplink time unit is the first non-SBFD time unit for downlink, the first SBFD time unit for downlink, or the first flexible time unit for downlink. It should be understood that, compared with the above-mentioned manner 1, considering that the first time unit indicated by the FDRA field is an uplink time unit in some communication scenarios, the TBS is determined according to the frequency resources corresponding to the first non-uplink time unit after the time unit.

[0226] For example, FIG. 2C is a schematic diagram of a TBS determination manner according to an embodiment of the present disclosure. The first information indicates that the first time unit of PDSCH time slot aggregation is an uplink time unit, and then the TBS is determined according to the first non-uplink time unit after the time unit. As shown in FIG. 2C(a), the first non-uplink time unit of PDSCH time slot aggregation indicated by the first information is a downlink time unit, and therefore the TBS is determined according to the number of PRBs indicated by the FDRA field in the first information, that is, n PRB is the number of PRBs indicated by the FDRA field.

[0227] For example, as shown in FIG. 2C(b), the first information indicates that the first time unit of PDSCH time slot aggregation is an uplink time unit, and then the TBS is determined according to the first non-uplink time unit after the at least one time unit. As shown in FIG. 2E, the first non-uplink time unit is an SBFD time unit, and then the TBS of the first signal is determined based on the number of remaining PRBs after the number of PRBs included in the uplink sub-band and / or the guard band is deducted from the number of PRBs indicated by the FDRA field corresponding to the first information.

[0228] In some embodiments, the available time unit in the above-mentioned embodiments can be a time unit other than an uplink time unit indicated by the first information, for example, a downlink time unit and / or a flexible time unit. It can also be a time unit for receiving the first signal determined based on a set conflict criterion, for example, based on the conflict criterion corresponding to the current network environment, it is determined that a certain time unit is an uplink time unit, but based on the first information, it is determined that the terminal receives the first signal on the uplink time unit, and then the uplink time unit is determined as an available time unit according to the conflict criterion.

[0229] Manner 3: The first time unit is a non-SBFD time unit in the at least one time unit, and the TBS of the first signal is determined according to the number of frequency domain resources on the non-SBFD time unit.

[0230] For example, the determination of the TBS in this embodiment is independent of the time unit type of the first time unit of the PDSCH time slot aggregation, and the TBS is always determined according to the number of frequency domain resources on the non-SBFD time unit indicated by the FDRA field corresponding to the first information. FIG. 2D is a schematic diagram of a TBS determination manner according to an embodiment of the present disclosure. As shown in FIG. 2D, regardless of the time unit type of the first time unit corresponding to the PDSCH time slot aggregation, the TBS is always determined according to the number of frequency domain resources on the non-SBFD time unit indicated by the FDRA field, that is, n PRB is the number of PRBs indicated by the FDRA field.

[0231] Scheme 4: The first time unit is an SBFD time unit in at least one time unit, and the TBS of the first signal is determined according to the number of available frequency domain resources on the SBFD time unit.

[0232] For example, the TBS of the first signal is determined according to the number of frequency domain resources available for downlink transmission in the frequency domain resources indicated by the FDRA field corresponding to the first information, regardless of the time unit type of the first time unit of the PDSCH time slot aggregation. FIG. 2E is a schematic diagram of a TBS determination manner according to an embodiment of the present disclosure. As shown in FIG. 2E, regardless of whether the time unit type of the first time unit in the PDSCH time slot aggregation is an SBFD time unit or a non-SBFD time unit, the terminal always determines the TBS according to the number of available frequency domain resources on the SBFD time unit indicated by the FDRA field, that is, n PRB is the number of PRBs indicated by the FDRA field.

[0233] Scheme 5: The first time unit is an SBFD time unit and a non-SBFD time unit in at least one time unit, and the terminal determines the TBS of the first signal according to the number of available frequency resources on the SBFD time unit + the number of available frequency resources on the non-SBFD time unit.

[0234] For example, FIG. 2F is a schematic diagram of a TBS determination manner according to an embodiment of the present disclosure. As shown in FIG. 2F, the number of frequency resources for PDSCH transmission in the first time unit is:

[0235] [According to Rule 91 Correction 15.10.2024] Wherein, K SBFD is the number of SBFD time slots allocated for the PDSCH time slot aggregation, K non-SBFD is the number of non-SBFD time slots allocated for the PDSCH time slot aggregation, n PRB,SBFDnPRB,SBFD is the number of available PRBs on SBFD slots, i.e., the number of PRBs indicated by the FDRA field minus the number of PRBs where the PRBs indicated by the FDRA field overlap with the uplink sub-band and / or guard band, nPRB,non-SBFD is the number of available PRBs on non-SBFD slots, i.e., the number of PRBs indicated by the FDRA field, [ ] is the rounding operation, which can be rounding up, rounding down or rounding, as shown in FIG. 2F(a).

[0236] For example, based on the above example, K SBFD is modified to the number of SBFD time units available in PDSCH slot aggregation, K non-SBFD is modified to the number of non-SBFD time units available in PDSCH slot aggregation, as shown in FIG. 2F(b), and the TBS of the first signal is determined in the above manner. The first uplink time unit cannot be used for transmission of PDSCH slot aggregation, and therefore the number of resources on this time unit is not included in the TBS calculation.

[0341] FIG. 4 is a flow diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 4, the embodiments of the present disclosure involve a communication method performed by a network device, and the above method includes:

[0342] In step S4101, the first information is sent to the terminal 101.

[0343] In some embodiments, the first information is used to instruct the terminal to receive the first signal on at least one time unit, and the first signal is carried by the PDSCH resource.

[0344] In some embodiments, the TBS of the first signal is determined by the terminal according to the frequency resource corresponding to the first time unit, and the first time unit is one or more of the at least one time unit.

[0345] In some embodiments, the at least one time unit includes an SBFD time unit and a non-SBFD time unit.

[0346] In some embodiments, the first time unit includes at least one of the following:

[0347] The first time unit in the at least one time unit;

[0348] a first non-uplink time unit in the at least one time unit;

[0349] a non-SBFD time unit in the at least one time unit;

[0355] In some embodiments, the first time unit is determined according to one or more bits corresponding to the highest bits of the FDRA field.

[0357] sending second information to the terminal device, the second information being carried by RRC information, wherein the first time unit is determined according to the second information.

[0358] In some embodiments, the other optional implementations described before or after the description corresponding to FIG. 4 can be referred to.

[0359] FIG. 5 is an interaction flow diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 5, the embodiment of the present disclosure relates to a communication method, and the above method includes:

[0360] Step S5101, the network device sends first information and a first signal to the terminal device, and the first information is used to instruct the terminal device to receive the first signal.

[0361] Step S5102, the terminal device receives the first information sent by the network device.

[0362] Step S5103, the terminal device receives the first signal sent by the network device according to the first information.

[0363] In some embodiments, the first signal is carried on a PDSCH, wherein the PDSCH adopts time slot aggregation, and the PDSCH time slot aggregation is respectively allocated on an SBFD time unit and a non-SBFD time unit, the SBFD time unit is a time unit configured with an uplink sub-band, and the non-SBFD time unit is a time unit without a configured uplink sub-band. It should be understood that the SBFD time unit refers to a time unit in which the network device performs SBFD operation, and the non-SBFD time unit refers to a time unit in which the network device does not perform SBFD operation, or in other words, the non-SBFD time unit refers to a time unit in which the network device performs TDD operation, and the non-SBFD time unit includes an uplink time unit, a downlink time unit, and / or a flexible time unit; in the absence of special instructions, the non-SBFD time unit generally refers to a downlink time unit and / or a flexible time unit.

[0364] Optionally, the first information includes an FDRA field, and the FDRA field indicates frequency domain resources for transmitting the first signal.

[0365] Optionally, the network device and the terminal device determine the TBS of the first signal according to the number of frequency domain resources indicated by the FDRA field, and the determination includes the following schemes:

[0366] Option 1: The TBS is determined according to the number of available frequency domain resources in the first time unit of the PDSCH time slot aggregation.

[0367] Optionally, if the first time unit of the PDSCH time slot aggregation is a non-SBFD time unit, the TBS is determined according to the number of frequency domain resources indicated by the FDRA field; otherwise, the TBS is determined according to the number of frequency domain resources available for downlink transmission in the frequency domain resources indicated by the FDRA field (the corresponding downlink sub-band resources are removed from the uplink sub-band and / or the guard band in the SBFD).

[0368] It should be understood that in the SBFD time unit, the uplink sub-band and / or the guard band cannot be used for downlink transmission, and if the frequency resources located in the uplink sub-band and / or the guard band are included in the frequency domain resources indicated by the FDRA field, these frequency domain resources are not included in the calculation of the TBS.

[0369] Optionally, the first information further indicates the position of the first time unit of the PDSCH time slot aggregation.

[0370] For example, as shown in FIG. 2B(a), the first information indicates that the first time slot of the PDSCH time slot aggregation is a downlink time slot, and the TBS is determined according to the number of PRBs indicated by the FDRA field, that is, the number of PRBs indicated by the FDRA field.

[0371] For example, as shown in FIG. 2B(b), the first information indicates that the first time slot of PDSCH time slot aggregation is an SBFD time slot, then the TBS is determined according to the number of PRBs indicated by the FDRA field, and then the number of PRBs included in the uplink sub-band and / or guard band is deducted, i.e., n PRB The number of PRBs indicated by the FDRA field is reduced by the number of PRBs of the PRBs indicated by the FDRA that overlap with the uplink sub-band and / or guard band.

[0372] Optionally, the terminal device does not expect the first information to indicate that the first time unit of PDSCH time slot aggregation is an uplink time unit. It should be understood that according to the method in Mode 1, if it is an uplink time unit, there is no frequency domain resource available for downlink transmission.

[0373] Mode 2: The TBS is determined according to the number of available frequency domain resources on the first available time unit of PDSCH time slot aggregation.

[0374] It should be understood that, compared with Scheme 1, Scheme 2 takes into account the determination of the TBS of PDSCH time slot aggregation in the case where the first time unit is an uplink time unit.

[0375] [Corrected according to Rule 91 on 15.10.2024] For example, as shown in FIG. 2C(a), the first information indicates that the first time slot of PDSCH time slot aggregation is an uplink time slot, then the TBS is determined according to the first non-uplink time slot after the time slot. The first non-uplink time slot is a downlink time slot, so the TBS is determined according to the number of PRBs indicated by the FDRA field, i.e., n PRB The number of PRBs indicated by the FDRA field.

[0376] [Corrected according to Rule 91 on 15.10.2024] For example, as shown in FIG. 2C(b), the first information indicates that the first time slot of PDSCH time slot aggregation is an uplink time slot, then the TBS is determined according to the first non-uplink time slot after the time slot. The first non-uplink time slot is an SBFD time slot, so the TBS is determined according to the number of PRBs indicated by the FDRA field, and then the number of PRBs included in the uplink sub-band and / or guard band is deducted, i.e., n PRB The number of PRBs indicated by the FDRA field is reduced by the number of PRBs of the PRBs indicated by the FDRA that overlap with the uplink sub-band and / or guard band.

[0377] Optionally, in addition to being defined as a non-uplink time unit, the available time unit can also be determined according to the existing conflict criteria.

[0378] Mode 3: The TBS is determined according to the number of frequency domain resources on a non-SBFD time unit.

[0379] It should be understood that the number of frequency domain resources indicated by the FDRA field is determined regardless of the first time unit type of the PDSCH time slot aggregation. For example, as shown in FIG. 2D, the TBS is always determined according to the number of PRBs indicated by the FDRA field, i.e., n PRB is the number of PRBs indicated by the FDRA field.

[0380] Method 4: The TBS is determined according to the number of available frequency domain resources on the SBFD time unit.

[0381] It should be understood that the number of frequency domain resources indicated by the FDRA field is determined regardless of the first time unit type of the PDSCH time slot aggregation. For example, as shown in FIG. 2E, the TBS is always determined according to the number of PRBs indicated by the FDRA field, i.e., n PRB is the number of PRBs indicated by the FDRA field.

[0382] Method 5: The TBS is determined according to the number of SBFD time units, the number of non-SBFD time units, and the number of available frequency domain resources on the two types of time units.

[0383] For example, the number of REs used for PDSCH transmission in a time slot is:

[0384] wherein K SBFD is the number of SBFD time slots allocated for the PDSCH time slot aggregation, K non-SBFD is the number of non-SBFD time slots allocated for the PDSCH time slot aggregation, n PRB,SBFD is the number of available PRBs on the SBFD time slot, i.e., the number of PRBs indicated by the FDRA field minus the number of PRBs indicated by the FDRA field that overlap with the uplink sub-band and / or the guard band, nPRB,non-SBFD is the number of available PRBs on the non-SBFD time slot, i.e., the number of PRBs indicated by the FDRA field, and [] is the rounding operation, including rounding up, rounding down, or rounding, as shown in FIG. 2F(a).

[0385] For example, in the above example, the modification is: K SBFD is the number of SBFD time slots available for the PDSCH time slot aggregation, K non-SBFD is the number of non-SBFD time slots available for the PDSCH time slot aggregation, as shown in FIG. 2F(b), wherein the first uplink time slot cannot be used for transmission of the PDSCH time slot aggregation, so the time slot is not included in the TBS calculation.

[0386] In some embodiments, the TBS is determined according to the number of available frequency resources on the indicated time unit type.

[0387] Optionally, the network device sends second information, which indicates which type of time unit the terminal device uses to determine the TBS based on the number of available frequency domain resources.

[0388] 1 bit: indicates one of two schemes in schemes 1-5;

[0389] 2 bits: indicates one of three or four schemes in schemes 1-5;

[0390] 3 bits: indicates one of five schemes in schemes 1-5;

[0391] Optionally, the first information also indicates which type of time unit the terminal device uses to determine the TBS based on the number of available frequency domain resources.

[0392] Method 1: multiplex 1 bit (or 2 bits) in the FDRA field to indicate which type of time unit the TBS is determined based on the number of available frequency domain resources

[0393] Type 0: Each bit in the bitmap is only associated with a resource block group (RBG) that overlaps with the downlink sub-band. At least 1 bit can be saved

[0394] Type 1: Add 1 bit (or 2 bits) to the highest bit of RIV, and use RRC to control the understanding of FDRA on the terminal device side

[0395] Method 2: Add 1 column in the TDRA table to indicate one of X schemes in schemes 1-5

[0396] It should be understood that the network device also determines the TBS based on the number of available frequency domain resources of the same type of time unit.

[0397] In the above manner, the problem of how to determine the TBS in the PDSCH time slot aggregation scenario in the prior art is solved. At the same time, the target code rate and the actual code rate can be ensured to be approximately consistent, which can ensure the PDSCH time slot aggregation performance while avoiding resource waste.

[0398] The embodiments of the disclosure also propose a device for implementing any of the above methods, for example, a device including units or modules for implementing each step performed by the terminal in any of the above methods. For another example, another device is also proposed, which includes units or modules for implementing each step performed by the network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0399] It should be understood that the division of each unit or module in the above apparatus is only a logical function division, and all or part of them can be integrated into a physical entity or physically separated in actual implementation. In addition, the units or modules in the apparatus can be implemented in the form of processor calling software: for example, the apparatus includes a processor connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to implement any of the above methods or realize the functions of the units or modules of the above apparatus, wherein the processor is a general processor such as a central processing unit (CPU) or a microprocessor, and the memory is a memory in the apparatus or a memory outside the apparatus. Alternatively, the units or modules in the apparatus can be implemented in the form of hardware circuit, and the functions of part or all of the units or modules can be realized by the design of the hardware circuit. The above hardware circuit can be understood as one or more processors; for example, in one implementation, the above hardware circuit is an application-specific integrated circuit (ASIC), and the functions of part or all of the units or modules are realized by the design of the logical relationship of the elements in the circuit; for another example, in another implementation, the above hardware circuit is a programmable logic device (PLD), and a field programmable gate array (FPGA) is taken as an example, which can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by a configuration file, so as to realize the functions of part or all of the units or modules.
